The MSCI ACWI ex USA Index includes companies domiciled in countries around the world, including companies in the Asia region, Europe and the U.K. The Fund may invest a significant portion of its total assets (5% to 50% under normal market conditions) at the time of purchase in securities issued by companies domiciled in emerging and frontier markets, which are those countries currently included in the MSCI EFM (Emerging + Frontier Markets) Index.
